2. Practice:
(1) Boil tomatoes with boiling water 1 min, and peel them. Cut in half, put half into a food supplement machine and mash, and cut the other half into cubes for later use.
(2) Cut the rape leaves and amaranth leaves into pieces.
(3) Mix the egg yolk, flour, chopped vegetable leaves and tomato paste evenly, or add a little water, and the thickness is determined by yourself.
(4) put in a small fresh-keeping bag.
(5) Pour the other half of diced tomatoes into the pot (no oil is added in the pot), stir-fry the juice with low fire, add boiling water, and turn to medium fire for boiling.
(6) Cut a small opening in the fresh-keeping bag, drip it into the boiling pot at a uniform speed, and cook for another 2 minutes.
